When you tap “send” in a banking app, the money does not travel directly from one bank to another in the way it appears. Payments go through shared systems, and which one is used decides how fast it arrives and what protections apply.
The three main UK systems
Faster Payments. Launched in 2008 and run by Pay.UK, it handles most everyday online and mobile transfers between UK accounts, as well as standing orders. Payments normally arrive within seconds, and the system operates every day of the year. The maximum for a single Faster Payment is £1 million, though banks set their own, usually much lower, limits for customers.
Bacs. The older system behind Direct Debits and most payroll runs. It works on a three-working-day cycle: payments are submitted, processed and then credited, which is why salary and Direct Debit dates are scheduled in advance. It is cheap and reliable for large batches but not suitable for urgent transfers.
CHAPS. A same-day, high-value system settled through the Bank of England’s real-time gross settlement service. It is used for property purchases, large business payments and other time-sensitive transfers, and it usually carries a fee. CHAPS payments must be made within the system’s working hours on business days.
Card payments run on separate networks, such as Visa and Mastercard, and are covered by different rules.
What happens behind the scenes
A transfer is an instruction to adjust balances, not a movement of physical cash. Your bank debits your account and tells the other bank to credit the recipient. The banks later settle the net amounts they owe each other through accounts at the Bank of England, which means the payment is backed by central bank money. For the customer, the credit usually appears immediately, but the final settlement between banks happens separately.
Why payments sometimes take longer
Most delays are not the system itself. They are checks. Banks screen payments for fraud and sanctions, and unusual, large or first-time payments can be held for review. A payment to a new payee, or for an amount far above normal activity, is more likely to be paused. Cut-off times matter for non-Faster-Payments routes, and some banks hold new or risky payments for further checks before release.
Confirmation of Payee
When you enter a sort code and account number, many banks now check the name you enter against the name on the receiving account and tell you whether it matches, closely matches, or does not match. Confirmation of Payee was introduced from 2020 for the largest banks and has been extended, with the Payment Systems Regulator requiring hundreds of further firms to adopt it. If the check says “no match”, stop and verify the details with the recipient through a channel you trust, before sending money.
Fraud and reimbursement
Since 7 October 2024, firms must reimburse many victims of authorised push payment fraud, where someone is tricked into sending money to a fraudster. The mandatory scheme covers payments sent through Faster Payments and CHAPS, with a maximum reimbursement of £85,000 per claim. Claims must be made within 13 months of the final payment, and some exceptions apply, for example where a customer has acted with gross negligence. Higher losses can be pursued through the Financial Ombudsman Service, which can make awards above that cap.
Practical points follow:
- Confirm payment details independently, particularly after receiving a change of bank details by email.
- Treat urgency as a warning sign. Genuine organisations do not demand an immediate transfer to a “safe account”.
- Use the Confirmation of Payee result as information, not decoration.
- Report suspected fraud to your bank immediately.
How the pieces fit with the rest of banking
Because domestic transfers are cheap to run, most banks do not charge for them, which is part of the picture in why banks charge different types of fees. Newer services built on the same infrastructure, including payments initiated by authorised third parties, are covered in what open banking means for UK consumers.
This is general information, not financial advice. Limits, fees and reimbursement rules vary by provider and change over time; check your bank’s terms.
